In Cuba Marchfi, 1943 p 2Claims. (Cl. 215-30) This invention relates to non-refillable bottles and like containers, and particularly to a nonrefillable closure of disc valve type.

This invention has for its object to provide an improvement in non-refillable closure, consisting in mounting the valve casing almost completely outside the bottle neck and with only a small, deep portion thereof fitted in thebottle mouth to center the valve casing, and in making the disc valve with a peripheral edge at its recessed lower face so that its contact with its seat-formed by the bottom of the valve casing will be firm and safe about the bottom central opening, whereby I obtain a simpler valve-casing structure and a more efilcient operation of the disc valve, thereby adding efiiciency to the closure to prevent refilling of the bottle.

The-invention is described with reference to the figures of the accompanying drawing, of which:

Fig. 1 is a diametral vertical section view oi -a bottle neck provided with a non-refillable closure embodying the improvement forming the subjectmatter of this invention, in .its raised or sealed position.

Fig. 8 is a perspective detailed view of the improved disc valve;

Figs. 9 and 10 are respectively a plan view and an edge view of the :catch ring forming the device for automatically locking the closure upon the bottle neck.

In the drawing, I indicates a bottle neck which has adjusted at its mouth a small deep portion of the bottom of a device of plastic material in the shape of a cylindrical cup 2 having a central hole 3 at its bottom portion and a peripheral recess 4 at its lower edge to fit on the mouth of the bottle neck I and at the same time to rest on a packing washer 5 disposed on the upper edge of bottle neck -I. The inner space-ofthe cup 2 serves as a lodging for a free valve consisting of asolid disc 6 of a diameter slightly smaller than the inner diameter. of the cylindrical body of the cup 2 to permanently allow the passage of liquid there about in any inclined position of the bottle, with the peculiarity that the lower face of. the disc 6 is recessed to form an annular peripheral edge 7 whereby its contact with the bottom portion of cup 2 serving as a seat for same is more firm and secure than would be .ifthe lower face of the disc 6 were entirely plain. v

The upper peripheral portion or the bottle neck ..I has screw threads :8 and thereon-is threadedly adjusted acylindrica1v cover 9 made of glass or another plastic material provided with an inner threaded groove l0 adapted to be screwed on the bottle screw threads 8. until allowingthe lower edge of a larger lower portion 9' of the cover 9 to rest on a marginal rim portion 1 l formed on an annular edge ll provided on the bottle neck I, said cover 9 having at its upper edge an inner horizontalflange l2 which is adapted to fit on an outer horizontal-flangefl3 formed on the lower edge of another cylindrical cover I 4 of smaller diameterthan the cover 9 and situated above.

Thecover I4 is provided near its lower edge with a horizontal partition which has near the inner surface of cover 14 four inter-equidistant openings l6 (Fig. 4)., the cover I4 having at its outer surface ascrew thread I! adapted to threadedly I receive the threaded groove oia thread cap J8, preferably metallic, which is adjusted on the upper edge of the .uppercover. l4 through. the intermission of a compressible disc I 9 to prevent liquid overflow in the closed position of the cap 18.

Between thelower edgeof the upper cover It and the up er; edge of the cup 2 is interposed a glass or another plastic material disc through the intermission of an upper packing washer 2| and another lower packing washer 22, said disc '20 having a central hole 23 and' four smaller quidistant holes 24, arranged in circular alignment about the central hole 23 (Fig. 5.), said disc 20 having also at its lower face four pointedprojections disposed alternately to the four encircling holes 24, the function of said projections 25 being to prevent the disc 6 from adheringlby its upper face to the lower face of the disc 20 upon the bottle being inclined. The upper cover I4 is so placed relatively to the disc 20 that the four openings I6 of the partition do not vertically register the four encircling holes 24 of the disc 20, to which end both the cover l4 and the disc 20 are secured in fixed position by means of a tongues 30 and CH which are alternatively inclined upwards and downwards to form opposed catches adapted to engage opposed ratchet gear crowns 32 and 33 formed respectively on the lower face of the horizontal flange 28 and on the upper face of the annular edge I I.

Assuming the catch ring 29 placed on the emu: j

lar edge I I in the position on which its downward catches 3| engage the upper ratchet gear crown 33 of the annular edge I l of the bottle neck I, the lower cover 9 is screwed on the bottle neck]; by causing it to rotate to theright or in 'a clockwise direction until the lower edge of the enlarged portion 9' of said cover 9 comes to reston the upper face of the annular edge II on its marginal rim portion I I, and the upwardly directed catches 30 of the catch ring 29 come to engage the lower ratchet gear crown 32 of the horizontal flange 28, whereupon the lower cover 9 will remain locked and it will be impossible to unscrew the lower cover 9 to withdraw it from the bottleneck I, the catch ring thus affording an eiTective locking means for undetachably securing the non-refillable closure to the bottle neckl, and the lower cover 9 must be broken away in order that 'the bottle may be refilled.

The present invention constitutes a further development of the bottle closure described in the copending application Ser. No. 478,339 of March a, 1943. 1
